KeyError in parseCVSSVector

[RasKalit0]

Excel file is indeed created and with useful information but I mentioned errors while running the script.

$ cat /etc/centos-release
CentOS Linux release 7.8.2003 (Core)

$ python3 --version
Python 3.6.8

Fetched https://github.com/fyrm/nepali/archive/master.zip, unzip, added some python modules that were missing and ran nepali.py against a sample .nessus report.
This nessus report header is:
<?xml version="1.0" ?><NessusClientData_v2>

Looking at the very first KeyError error occurrence (KeyError: 'PR:N') I see that PR:N is defined in cvss3_keyvalue_dict and use in parseCVSSVector(vector)

Am I the only one facing this issue?

Thanks and best regards,
